Kalle Rovanperä achieves second consecutive podium finish for TOYOTA GAZOO Racing at Ypres Rally in Belgium
How they work
In the past, ignition systems used a spark distribution system in which the high voltage generated by an Ignition Coil was distributed to the spark plugs by a distributor. Today’s engines feature a Distributor-Less Ignition (DLI) system, delivering high voltage directly from the ignition coils to the spark plugs. For engines with an electronic ignition system, DLI systems create a high voltage by using a coil with an igniter (Stick Coil) that isdirectly mounted onto the spark plugs in the cylinders.
The Ignition (Stick) Coil is a type of transformer, consisting of:
> a primary coil that changes electrical energy into magnetic energy.
> a core (iron) that acts as a magnetic circuit to accumulate magnetic energy.
> a secondary coil that converts magnetic flux variations as electrical energy into high voltage.
